Jan 23, 2012 Step 7 Processing (on-site) Once ore is extracted, processing it into pure gold must be done. Ore is first crushed and then undergoes various processes depending on the nature of associated minerals. Processing low-grade ore is relatively simple while higher grades require more extensive processing.
Processing is where mines are made or broken and reducing process costs without reducing recovery is what sets apart experience from book Learning. ...

The worlds gold production has changed over the past 30 years. The exploration and discovery of large, free-milling gold deposits in major mining districts has declined. Mining companies face a difficult decision. Do they process large, low-grade deposits or look for smaller, often more complex ones in remote, often hard-to-reach locations?
Gold CIL processing plant Carbon in Leach (CIL) process is widely used in the mining industry and in particular, it is an integral step of gold processing in gold extraction. Normally the CIL process can concentrate gold from 2.53.5 g/t in ore to 2000 to 6000 g/t on carbon.
